Axial Turbine Stage Characteristics

open access: yesNTU "KhPI" Bulletin: Power and heat engineering processes and equipment, 2018
Today the energy consumption structure requires using the turbine units of thermal power plants of a high power to regulate the energy system frequency and power that drop by 35 to 40 % of the rated load during the night time or stop. Nevertheless, turbine stages operate in a wide range of the mode variation ranging from those that exceed the nominal ...
